ATo all. @from t fniag/ concern; Y r n Be' it known that I', kRALPH DE Bonn, a citizen of the United States, residing .at

Sheldon, inthe county. of OBri'en and State of Iowa, have, invented certain new and use- .ful Improvements in Four-Horse Eveners,

of whichL the following is specification, reference being had therein to the accompany.- ing drawings.

This invention relates to a four-horse hitch for use -for a two-row `cultivator. f v

The object of. the invention is the con` struction of a simple andl eliicient-evener` apparatus, which ,canbe attached to a cultivator by a pair of bolts,`and whichevener operates vto even the strain'of thevteams should one team pull ahead of thek other,

causing a steady strain `or `pulling action upon the cultivatonresulting in the kcultivator being drawn straight .ahead f. at all times;` V l M` With this and othery objects lin view, my invention comprises certain novel combinar tions, constructions andl arrangements of the arrows. v

Figure l is a sectional view, taken on line 4 4, Fig. 3, and looking in the direction ofthearrows. n 1. W

Referring to the drawings by'numerals, 1 1, designates the beamsrof ythe cultivator.

apparatus comprises a pair of substantially L-shaped, upper lever arms 2, and a pair of. lower, L-shaped lever arms 3. These lever'arms 2 and 3 are lsupported upon oppo-y site sides of the beams l, by means of bolts The upper lever arms 2 have their inner ends bent upwardly, at 5, and these inner ends extend into bifurcations '6 fo-rmed in the ends of the upper connecting link .7. v

Rivets 8 extend through the ends of link 7, and the inner ends of` lever arms 2. p-ivotally connect the saine together.

`Whil`e the'inner ends ofthe upper lever arms extend inwardly (Fig. l), the inner ends of the'lowerV lever arms 3 extendioutwardly,

and againstthese outwardly-extending inner .endsbears the 4lower connecting'link "9.'

Plates 10 arelaid against the link 9 and i the inner endsfof arms 3and by'meansy of rivets ll, the arms 3, plates 10 and link 9 are fastened together. Double trees l2 are vpivotally mounted, by bolts or rivets 13, bef` tween the outer ends of the upper lever arms 2 and. the lower lever arms 3. Suitably mounted lupon the double trees 12are single trees 14;' y

The draft animals are hitched to the single trees 14,*and inthe event of either pair pulling aheadof the other pair,r` the evenerv will 'distribute' the strain, resulting in the cultivatorpulling straight ahead.

While I have described thepreferred embodiment of my invention, and have illus-l trated the same in the accompanying drawings, certain minor changes or alterations may appear rto one lskilled in lthe art to which this invention relates, during the eX- n f tensivermanufacture of the` same and I,

therefore, reserve the right to make such alterations or changes as shall fairlyxfall within the scope of the 'appended claims.

. Vhat I claim is:

. l.. In an apparatus of the class described,v

the combination of a pair of cultivator beams, a pair ofupper, L-'shapedlever arms resting on said beams, the inner 'ends of said lever arms extending inwardly between the beams, a pair of lower, L-shaped lever arms against the beams, the inner ends of said lever arms. extending outwardly between thebeams, an upper link provided with bifurcations in its ends, the inner ends of ysaid upper lever arms in said bifurcations, means pivotally connecting'the inner ends of the upper lever arms` and the ends `of said connecting link, a lower link against the inner ends of the lowerlever arms be -tweenthe beams, plates on said lower link andy said inner ends ofthe lower lever arms,

fastening means yconnecting the lower lever arms', lower link and plates together, and

`draft animal connecting means'pivotally seico cured 'between the outer ends of said upper 'i and lower lever arms.

the combination with a pairof cultivator beams,kof L-shaped, upper lever arms pivotally mounted on said'beams, said'lever 2. In anapparatus ofthe class described,

arms provided with inner, upwardly-extending ends between the beams, a bifurcated connecting link on said upwardly-extending ends, lower, L-sliaped lever arms pivotally mounted on said beams, a connecting link connecting the inner ends of said lower lever i arms, double trees between the outer yends of said upper and lower vlever arms, and means pivotallyk fastening said double trees on saidarms. i

3. In an apparatus ol the class described, the combination with a `pair oficultivator beams, of upper and lower lever .arms on said beams, said upper lever arms and lower lever arms having their inner ends positioned between the beams and extending in signature.
